I think the main issue is still lack of law and order. Like kwarc said, too many people go scot free in Nepal. This emboldens the general public to commit crimes. Illegal weapons are available and can be used to threaten victims with dire consequences if they dont comply. Nepal has become a lawless land, this is especially true in the countryside where there are different political parties playing around. They have become a law themselves. Politics has emboldened the general populace but negatively.
These political goons need to reflect. Society in general needs to reflect. Someday it will be your own daughter, sister, mother who will be victim. 
Nepal at present needs a dictator like Saddam Hussein or Hitler. I feel sad to say this but there appears to be no other solution.
